Chromis chromis (Castagnole)

Chromis chromis fish, also called chromis chromis, is a fish from the pomacentridae family. It is commonly called "damoiselle de chromis" because of its blue color and its fins similar to those of a damoiselle. The chromis chromis measures about 15 cm long and has an elongated and slender shape. Her dress is mainly blue, with white stripes on the sides and a dark strip through the eyes. The pectoral and pelvic fins are transparent, while the back and caudal fins are blue.

The chromis chromis lives in the tropical and subtropical waters of the Indian Ocean and the Pacific Ocean. It is mainly found in coral reefs, where it feeds on plankton, small crustaceans and small molluscs. The chromis chromis is generally lonely, although it can also come together in large benches to protect itself from predators.

Chromis chromis is a popular fish in the aquariophilia. It is generally peaceful and can be maintained in community aquarium with other fish of peaceful reefs. However, he can become territorial towards his fellows when confined to a limited space, so it is important to provide him with enough space to move and hide.

Due to its beauty and peaceful behavior, chromis chromis is often used in public aquariums to attract visitors. It is also considered an indicator of the health of coral reefs, because its presence can be a sign that the environment is conducive to marine life. However, as it is sensitive to changes in the environment, it can be affected by the overexploitation of marine resources and the destruction of coral reefs.
